Cell Lab 4N5 (99.995%) Lead (Pb) Pieces Evaporation Materials

High-Purity Lead for Semiconductor, Photovoltaic, and Infrared Applications

General Description

Cell Lab 4N5 (99.995%) Lead (Pb) Pieces are ultra-high-purity evaporation materials ideal for thin-film deposition, infrared detection, and photovoltaic fabrication. Lead’s unique combination of high density, softness, and low melting point (328 °C) makes it an excellent material for controlled evaporation processes.

In semiconductor and optoelectronic applications, lead-based compounds such as PbTe and PbSe are critical for IR sensors and thermoelectric devices. Its superior film uniformity and compatibility with common crucible materials make it a reliable source for precision coating systems in vacuum environments.

Key Features

  • Ultra-High Purity (99.995%) – Ensures minimal contamination in thin-film growth.

  • Low Melting Point (328 °C) – Enables energy-efficient evaporation with stable deposition control.

  • Excellent Electrical Properties – Ideal for infrared detectors, solar cells, and thermoelectrics.

  • Stable Performance – Compatible with W, Mo, and Ta boats or Al₂O₃ crucibles for multiple setups.

  • Versatile Application Range – Suitable for use in semiconductor, optical, and coating research.

FAQ

Q1: Is lead safe to handle during evaporation?
Lead should be handled under controlled ventilation with protective gloves and fume extraction due to its toxicity.

Q2: What crucibles are best suited for lead evaporation?
Al₂O₃ crucibles or W/Mo boats are recommended for optimal compatibility and stability.

Q3: Can lead be co-evaporated with other elements?
Yes. Lead is often co-evaporated with Se or Te to form compound semiconductors such as PbSe or PbTe.

Q4: Does Cell Lab offer size customisation?
Yes. Particle size, purity grade, and packaging quantities can be fully customised for R&D or production use.
